Examples

The following example writes the contents of all of the response headers to the console.

// Creates an HttpWebRequest for the specified URL.
HttpWebRequest^ myHttpWebRequest = dynamic_cast<HttpWebRequest^>(WebRequest::Create( url ));

// Sends the HttpWebRequest and waits for response.
HttpWebResponse^ myHttpWebResponse = dynamic_cast<HttpWebResponse^>(myHttpWebRequest->GetResponse());

// Displays all the headers present in the response received from the URI.
Console::WriteLine( "\r\nThe following headers were received in the response:" );

// Displays each header and its key associated with the response.
for ( int i = 0; i < myHttpWebResponse->Headers->Count; ++i )
   Console::WriteLine( "\nHeader Name: {0}, Value : {1}",
      myHttpWebResponse->Headers->Keys[ i ],
      myHttpWebResponse->Headers[ (System::Net::HttpRequestHeader)i ] );

// Releases the resources of the response.
myHttpWebResponse->Close();
// Creates an HttpWebRequest for the specified URL. 
HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create(url); 
// Sends the HttpWebRequest and waits for response.
HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse(); 
                        
// Displays all the headers present in the response received from the URI.
Console.WriteLine("\r\nThe following headers were received in the response:");
// Displays each header and it's key associated with the response.
for(int i=0; i < myHttpWebResponse.Headers.Count; ++i)  
	Console.WriteLine("\nHeader Name:{0}, Value :{1}",myHttpWebResponse.Headers.Keys[i],myHttpWebResponse.Headers[i]); 
// Releases the resources of the response.
myHttpWebResponse.Close(); 
    ' Creates an HttpWebRequest with the specified URL. 
    Dim myHttpWebRequest As HttpWebRequest = CType(WebRequest.Create(url), HttpWebRequest)
    ' Sends the HttpWebRequest and waits for a response.
    Dim myHttpWebResponse As HttpWebResponse = CType(myHttpWebRequest.GetResponse(), HttpWebResponse)
    ' Displays all the Headers present in the response received from the URI.
    Console.WriteLine(ControlChars.Lf + ControlChars.Cr + "The following headers were received in the response")
    'The Headers property is a WebHeaderCollection. Use it's properties to traverse the collection and display each header.
    Dim i As Integer
    While i < myHttpWebResponse.Headers.Count
        Console.WriteLine(ControlChars.Cr + "Header Name:{0}, Value :{1}", myHttpWebResponse.Headers.Keys(i), myHttpWebResponse.Headers(i))
i = i + 1
    End While
    myHttpWebResponse.Close()

Remarks

The Headers property is a collection of name/value pairs that contain the HTTP header values returned with the response. Common header information returned from the Internet resource is exposed as properties of the HttpWebResponse class. The following table lists common headers that the API exposes as properties.
